FIELD OF THE INVENTION

The present disclosure relates generally to online shopping, and more particularly, to systems and methods for retrieving online merchant terms of a merchant and associating the online merchant terms with transactions.

BACKGROUND

Online shopping and online selling are increasing in popularity due to convenience and a wide range of product and service offerings. Merchants generally have terms and policies for their online shops, such as return policies, shipping policies, product warranties, and the like. These online merchant terms are typically posted on a web page of the merchant's web site of the merchant where a user or customer can access them. However, these online merchant terms are often not conspicuous and it is not usually obvious when they are updated. Merchants can change their online merchant terms at any time, which can lead to problematic scenarios such as an immediate change to a shipping policy or return policy after a customer makes a purchase. For returning customers, they may be unaware of changes to the online merchant terms that might affect them.

These and other deficiencies exist. Accordingly, there is a need to provide systems and methods that overcome these deficiencies to increase accessibility of up-to-date online merchant terms of merchants for transactions.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

The following description of embodiments provides non-limiting representative examples referencing numerals to particularly describe features and teachings of different aspects of the invention. The embodiments described should be recognized as capable of implementation separately, or in combination, with other embodiments from the description of the embodiments. A person of ordinary skill in the art reviewing the description of embodiments should be able to learn and understand the different described aspects of the invention. The description of embodiments should facilitate understanding of the invention to such an extent that other implementations, not specifically covered but within the knowledge of a person of skill in the art having read the description of embodiments, would be understood to be consistent with an application of the invention.

Example embodiments of the present disclosure provide systems and methods for retrieving online merchant terms of merchants, and associating the online merchant terms with corresponding merchants in a data store through, for example, corresponding merchant records for a date range. The online merchant terms are further associated in the data store with user transactions from corresponding merchants, which can be viewed in an interface, such as a bank or credit card statement interface.

The online merchant terms may be retrieved on a regular time interval basis using a screen scraper, an application programming interface (API), or other methods. Each retrieved version of the online merchant terms may be analyzed against a previous version of the online merchant terms stored in the data store to check for differences. If there are no differences, the recently retrieved version of the online merchant terms may be discarded, and the previous version of the online merchant term may then be referred to as the latest version. The date range previously listed for the previous version of the online merchant term may remain the same for the latest version of the online merchant terms. Alternatively, the date range previously listed for the previous version of the online merchant term may be adjusted to be a new date range for the latest version of the online merchant terms, because no differences are identified and the previous version can be expected to remain effective. For example, the end date of the date range previously listed for the previous version may be extended for a certain period of time (e.g., 30 days), such that the new date range is longer than the date range previously listed for the previous version.

If there are differences, the recently retrieved version of the online merchant terms can then be referred to as the latest version of the online merchant terms to replace the previous version of the online merchant terms. A new date range may be assigned to the latest version of the online merchant terms. This new date range may include a start date on which the recently retrieved version is retrieved. The previous version may be discarded if there are no transactions associated with it, which may reduce the need for storage space. However, the previous version may be retained if there have at least one transaction associated with it. If the previous version is retained, a new end date may be assigned to the date range listed for the previous version. This new end date of the previous version may be the date on which the recently retrieved version is retrieved. That is, this new end date of the previous version is the start date of the latest version, such that a new version of the online merchant terms (i.e., the latest version different than the previous version) has an assigned start date of the date on which the recently retrieved version is retrieved, and the previous version has an assigned end date of the date on which the recently retrieved version is retrieved.

When a user opens their bank or credit card statement interface, the user can select an option to review the relevant version of online merchant terms associated with their transactions, for example, purchases they made from corresponding merchants.

In some embodiments, merchants may have online merchant terms that are different from in-store merchant terms. In such scenarios, if no online merchant terms for in-store transactions are available, then the “view terms” option, for example, on the bank or credit card statement interface of the user may be excluded. The user may also elect to monitor the online merchant terms of a merchant and be notified if there is a change to the online merchant terms. Additionally, intelligent triggers may be used to retrieve the online merchant terms at relevant times (e.g., changes in regulation/law, company acquisitions, email triggers, etc.).

Accordingly, embodiments of the present disclosure may advantageously provide the user with easy access and ease of reference to online merchant terms, and to the applicable and relevant versions of those terms. By keeping the user apprised of the current terms and/or applicable terms, embodiments of the present disclosure can promote exercise by the user of his or her rights and options under terms and policies, etc. and reduce the cost and effort associated required to do so. Often users may not make an effort to save or otherwise keep track of online merchant terms, and such users will benefit from embodiments of the present disclosure.

In some embodiments, the online merchant terms may be scraped when a user transaction is received. That is, a scrape of the online merchant terms may be triggered by a user transaction. As described above, the scraped online merchant terms may be analyzed against a version of the online merchant terms currently stored and effective in the data store to check for differences. If there are no differences, the scraped online merchant terms may be discarded. If there are differences, the scraped online merchant terms can then be saved as a new version in the data store to replace the version currently stored in the data store. A new date range may be assigned to the scraped online merchant terms. This new date range may include a start date on which the scraped online merchant terms is stored in the data store. This may ensure the effective dates for the scraped online merchant terms, while still reducing storage required.

In some embodiments, the online merchant terms can be scraped periodically without requiring a transaction to prompt it. For example, the online merchant terms may be scraped hourly, daily, weekly or monthly. As described above, each time when the online merchant terms is scraped, the scraped online merchant terms may be analyzed against a version of the online merchant terms currently stored and effective in the data store to check for differences. If there are no differences, the scraped online merchant terms may be discarded. If there are differences, the scraped online merchant terms can then be saved as a new version in the data store to replace the version currently stored in the data store. A new date range may be assigned to the scraped online merchant terms. This new date range may include a start date on which the scraped online merchant terms is stored in the data store. This may ensure the effective dates for the scraped online merchant terms, while still reducing storage required.

Exemplary front channels include, without limitation, the Internet, an open network, and other publicly-accessible communication networks. In some examples, communications sent using a front channel may be subject to unauthorized observation by another device. In some examples, front channel communications may comprise Hypertext Transfer Protocol (HTTP) secure socket layer (SSL) communications, HTTP Secure (HTTPS) communications, and browser-based communications with a server or other device.

A secure back channel may be a communication protocol that employs a secured and/or publicly inaccessible communication channel. A secure back channel communication sent to the user device 110, server 120, and/or merchant device 140 may not originate from any device, and instead may only originate from a selective number of parties. In some examples, the selective number of devices may comprise known, trusted, or otherwise previously authorized devices. Exemplary secure back channels include, without limitation, a closed network, a private network, a virtual private network, an offline private network, and other private communication networks. In some examples, communications sent using a secure back channel may not be subject to unauthorized observation by another device. In some examples, secure back channel communications may comprise Hypertext Transfer Protocol (HTTP) secure socket layer (SSL) communications, HTTP Secure (HTTPS) communications, and browser-based communications with a server or other device.

In some examples, the user device 110 can be associated with a user and may be operated by that user, such as a customer. The server 120 can be associated with a financial institution, such as a bank or a credit card company that offers financial services to the user of the user device 110. The merchant device 140 can be associated with a merchant with which the user of the user device 110 may conduct transactions, and may be operated by that merchant, such as an online retailer.

FIG. 2 illustrates a method 200 of retrieving online merchant terms of a merchant and associating the online merchant terms with transactions according to an example embodiment. FIG. 2 may reference the same or similar components as those illustrated in FIG. 1 , including a user device, a server, a database, and a merchant device.

When a user makes a purchase online from a merchant, there may be online merchant terms of that merchant associated with that purchase. For example, the online merchant terms may include some type of agreement that requires the user to enter into with that merchant. An example of the agreement may be that the user would have to pay upfront for a service purchased from the merchant (e.g., a user rents a car online from a car rental agency). Other examples of online merchant terms may include: a merchant may warrant their service for a certain amount of time; a merchant may set policies for whether or not they accept returns and how those returns are going to work; whether they have a restocking fee on a return; how long a user has to choose whether or not to return a product; and the like.

However, these online merchant terms may be many pages of legalese and the user may not remember what the online merchant terms are by the time that the user seeks to exercise his or her rights under the online merchant terms, especially if a significant period of time has elapsed. For example, the user may have bought something a week ago, a month ago, or a year ago, and the online merchant terms changed after that purchase. Therefore, the user needs the ability to be able to look up what the online merchant terms were that are applicable to their purchase. That is, the user may need to know what the online merchant terms were at the time of the purchase which may have been made a long time ago, in order to assess their options with respect to that purchase. Herein, the method 200 describes an example embodiment of providing the user the online merchant terms that were effective at the time when their purchases were made.

In step 205, the server 120 may retrieve a first version of online merchant terms associated with a merchant. For example, upon receiving a transaction of the user who may purchase something from the merchant device 140, the server 120 may retrieve the online merchant terms associated with the transaction of the user. The server 120 may be, for example, a credit card company that issues a credit card to the user who uses the credit card to pay the transaction. When the merchant charges to the credit card of the user for the transaction, the server 120 receives the transaction that may include information indicative of the merchant based on which the server 120 may retrieve the online merchant terms. Alternatively, the server 120 may retrieve the online merchant terms based on a merchant already stored in the database 130 even if a transaction associated with the merchant has not been received. For example, a merchant may be a popular merchant to users, and users may have a highly likelihood of conducting transactions with that merchant in the future, the server 120 may then generate a merchant record for that merchant that may include a name and address of the merchant and a website link of the merchant, and store the merchant record of the merchant in the database 130. The server 120 may then retrieve the online merchant terms based on the merchant record of the merchant. Alternatively, the server 120 may retrieve the online merchant terms based on history of transactions associated with the merchant that have been stored in the database. The server 120 may retrieve the online merchant terms through the term retrieval module 1231 of the application 123.

The server 120 may retrieve the online merchant terms using different methods and techniques. For example, the server 120 may web-scrape the first version of the online merchant terms by accessing a uniform resource locator (URL) web page on which the first version of the online merchant terms is presented. In some embodiments, the server 120 may retrieve the online merchant terms by receiving a URL link from the user and then accessing the URL link to locate a web page on which the first version of the online merchant terms is presented. In some embodiments, the server 120 may retrieve the online merchant terms by calling an application programming interface (API) through which the first version of the online merchant terms is accessed by the server. In some embodiments, the server 120 may retrieve the online merchant terms by web-crawling the World Wide Web to locate a web page on which the first version of the online merchant terms is presented. Details of retrieving the online merchant terms using different methods and techniques will be described in FIG. 3 .

In step 210, the retrieved first version of the online merchant terms is stored in the database 130. The retrieved online merchant terms may be further formatted and indexed in the database 130. The retrieved online merchant terms may be stored in the database 130 as various forms, which may include but not limited to, a text file, a structured data format (e.g., an Extensible Markup Language (XML) document, a JavaScript Object Notation (JSON) document), and so forth. In addition, the retrieved online merchant terms may also be stored as a portable document format (PDF) file, an image file, an audio file, a video file, and/or an audio-video file in a file storage location such as a cloud storage offered by a cloud computing service provider. The database 130 may store links to the files stored in the file storage location.

In step 215, the server 120 may apply a first time stamp to the first version of the online merchant terms in the database 130. The first time stamp is indicative of a retrieval time and a retrieval date at which the first version of the online merchant terms is retrieved. The server 120 may also apply a second time stamp to the first version of the online merchant terms. The second time stamp is indicative of a storage time and a storage date at which the first version of the online merchant terms is stored in the database 130. The first and second time stamps may be the same or may be different. For example, when the server 120 retrieves the online merchant terms and does not store them in the database 130 soon enough, the first and second time stamps can be different. The first and second time stamps can be in various time formats, such as a 12-hour format, a 24-hour format, and the like.

In step 220, the server 120 may associate the first version of the online merchant terms with the merchant in the database 130. For example, the server 120 may associate the online merchant terms with the merchant through a merchant record of the merchant stored in the database 130. The merchant record may be a record comprising the merchant name, merchant address, merchant domain name, merchant identification, and the like.

In step 225, the server 120 may assign the first version of the online merchant terms a first date range in the database, wherein the first date range is indicative of a date range when the first version of the online merchant terms is effective in the database 130. For example, the first version of the online merchant terms may be stored in the database for the first date range (e.g., 180 days, one year, or the like). When the first date range expires, the first version of the online merchant terms may be discarded, archived, updated or retained. If the online merchant terms are updated or retained, a new date range may be assigned by the server 120. The date range is a time duration of the first version of the online merchant terms being stored in the database 130, which may not be the actual effective date range of the online merchant terms. For example, the first version of the online merchant terms may have taken effect by the merchant before the first version of the online merchant terms is retrieved and stored in the database 130 by the server 120.

In step 230, the server 120 may receive information of a first transaction of a user to identify a transaction time and a transaction date of the first transaction. The information of the first transaction may comprise the transaction time and the transaction date of the first transaction and a merchant identifier indicating the first transaction as being a transaction from the merchant. The transaction time and the transaction date of the first transaction are identified by extracting the transaction time and the transaction date of the first transaction from the information of the first transaction.

The server 120 may receive the information of the first transaction from the user device 110 through the application 113. For example, when the user of the device 110 receives the information of the first transaction from the merchant, the user of the device 110 may transmit the information of the first transaction to the serer 120. The information of the first transaction may be included in an electronic product or service receipt the user received from the merchant, an electronic order message the user received from the merchant, an electronic shipping message the user received from the merchant, or the like.

The server 120 may receive the information of the first transaction from a sale terminal associated with the merchant. For example, when the user shops online on a web portal of the merchant, the web portal may transmit the information of the transaction to the server 120.

The server 120 may also receive the information of the first transaction from the merchant device 140 through the application 143. For example, the merchant device 140 may receive the information of the transaction from a shopping terminal associated with the merchant, and transmit the information of the transaction to the server 120.

In step 235, the server 120 may search, based on the information of the first transaction, the database 130 for the first version of the online merchant terms. After the first version of the online merchant terms is stored and associated with the merchant in the database 130, the server 120 may search the database 130 for the first version of the online merchant terms when receiving the first transaction. The server 120 may identify the merchant name from the information of the first transaction, and search the database 130 according to the identified merchant name. By the merchant name, the online merchant terms associated with the merchant can be located in the database 130. If no online merchant terms associated with the identified merchant name is found in the database 130, the method 200 may flow back to the step 205 in which the online merchant terms associated with the identified merchant name can retrieved.

In step 240, the server 120 may determine whether the first version of the online merchant terms is applicable to the first transaction based on the time stamp of the first version of the online merchant terms, the first date range, and the transaction time and the transaction date of the first transaction. After the first version of the online merchant terms is located in the database 130, the server 120 may determine whether the first transaction falls within the relevancy time period, for example, the first date range assigned to the online merchant terms. If the online merchant terms are determined to be applicable to the transaction, the method 200 proceeds to the next step. If the online merchant terms are determined not to be applicable to the transaction, the method 200 flows back to the step 205 in which another version or copy of the online merchant terms that is applicable to the transaction may be retrieved.

In some embodiments, there may be multiple copies of the merchant online terms associated with the merchant stored in the database 130. Each copy of the online merchant terms may have been assigned a different date range and/or may be applicable to different transactions involved with the merchant. In such scenario, the server 120 may determine which copy of the online merchant terms is applicable to a transaction, for example, by comparing the time stamp of the transaction to the data range of a copy of the online merchant terms. The applicability of the online merchant terms may also be filtered based on whether a transaction is a card-present transaction or not a card-present transaction. For instance, a user may buy things from a merchant in store or may buy things from the merchant online. If the transaction is a card-present transaction indicating that the user physically handed the card at a point of sale terminal, then the transaction may not be bound by the online merchant terms. If the transaction is not a card-present transaction (i.e., an online transaction), then the transaction may be further determined to be bound by which copy of the online merchant terms based on the time stamp of the transaction and the date range of that copy (e.g., whether the transaction time falls within the time period of the date range of that copy of the online merchant terms).

In step 245, the sever 120 may associate in the database 130 the first version of the online merchant terms with the first transaction upon determining that the first version of the online merchant terms is applicable to the first transaction. The server 120 may perform the association through the term association module 1232 of the application 123 in FIG. 1 .

The online merchant terms associated with the transaction may be exposed through some type of URL incorporating query parameters. The query parameters may be determined based on the information of the transaction, for example, the merchant name, the transaction date and time, and so forth. As illustrated in FIG. 4 , an example of a user transaction in which a credit card is used to purchase something of $50 from merchant-1 on Mar. 20, 2020, a URL incorporating the name of merchant-1 and transaction date as query parameters of http://www.database130.com?name=merchant-1&date=03-20-20 (block 410 in FIG. 4 ) can expose the terms associated with this transaction. This URL can be designated to refer to the online merchant terms-1 that is still effective in the database 130 on Mar. 20, 2020 (i.e., the transaction time Mar. 20, 2020 falls within the date range of the online merchant terms in the database 130). Alternatively, the date of Mar. 20, 2020 in the query parameters may be other dates as long as a date can indicate the online merchant terms-1 are still effective on the transaction date in the database 130. For example, an expiration date (e.g., Jun. 20, 2020) of the online merchant terms can be used as a date in the query parameters, which is a date later than the transaction date of Mar. 20, 2020. Further, the query parameters may include other parameters such as a transaction identification (ID).

In some embodiments, a regular URL that does not contain query parameters may be specified for exposing the association of the online merchant terms with the transaction. For example, as shown in block 420 of FIG. 4 , for a user transaction in which a credit card is used to purchase something of $100 from merchant-2, a regular URL of http://www.database130.com/merchant-2-terms can be associated with the terms of this transaction. This association can be designated to refer to the online merchant terms-2 stored in the database 130 that is applicable to this transaction.

The regular URL and/or the URL containing query parameters may be limited to a certain number of visiting times out of security reasons. For example, the URL may stop working after it is clicked on 10 times. The URL may be private in some way where the user is required to log in in order to see the online merchant terms associated with that transaction. The URL may reference an API that exposes the online merchant terms stored in the database 130.

In some embodiment, instead of URL links, an interface including at least one button indicative of reviewing the online merchant terms may be used for exposing the associated online merchant terms with the transaction. For example, as shown in FIG. 5 , unlike the URL links in FIG. 4 , a button 510 and a button 530 may be used to expose the associated online merchant terms of merchant-1 and the online merchant terms of merchant-2 with corresponding transactions.

Like the URL links in FIG. 4 , the buttons 510 and 530 may be limited to a certain number of visiting times out of security reasons. For example, the buttons 510 and 530 may each stop working after it is clicked on 10 times. The buttons 510 and 530 may also be private in some way where the user is required to log in in order to see the online merchant terms associated with that transaction. The buttons in FIG. 5 may reference an API that exposes the online merchant terms stored in the database 130.

In step 250, responsive to receipt of a selection of viewing online merchant terms associated with the first transaction, the server 120 transmits the first version of the online merchant terms for display to the user. For example, the server 120 may be associated with a credit card financial institution that issues a credit card to the user. The user may then check the user's credit card transaction statement by logging into the server 120 from the user device 110. The user may be presented by the server 120 on the display of the user device the transaction history of the user, for example, in a PDF file for either last six months, or a year, or the like. In the transaction history, each transaction is associated with the online merchant terms of the corresponding merchant involved in that transaction. When the user determines to view the online merchant terms associated with that transaction, the user may make a selection of reviewing the online merchant terms. In response to the selection of the user, the server 120 transmits the online merchant terms to the user device 110 for display to the user. In the situations where the buttons 510 and 530 are used to expose the online merchant terms, the user may be presented by the server 120 on the display of the user device the transaction history of the user, for example, on an interactable web page for either last six months, or a year, or the like.

FIG. 3 illustrates a sequence flow diagram 300 of retrieving by the server 120 the online merchant terms using different methods and techniques. For example, the server 120 may web-scrape the first version of the online merchant terms by accessing a uniform resource locator (URL) web page (web-hosting server 1) on which the first version of the online merchant terms is presented (block 310). The web page may be hosted by the merchant device 140 or by a third-party associated with the merchant. When the URL web page on which the first version of the online merchant terms is known to the server 120, the server 120 may get the URL and go to the merchant's website to download the online merchant terms, for example, by copying the body of that web page. The URL may be further cached in the server 120 for further access in the future.

In some embodiments, the server 120 may retrieve the online merchant terms by receiving a URL link from the user (via user device 110) and then accessing the URL link to locate a web page on which the first version of the online merchant terms is presented (block 320). Upon receiving a transaction of the user who may purchase something from the merchant device 140, the server 120 may query the database 130 to check if the online merchant terms applicable to the transaction of the user is available in the database 130. If the online merchant terms applicable to the transaction of the user is not available in the database 130, the server 120 may request the user to provide the online merchant terms applicable to the transaction of the user. For example, the user may provide a URL link to the online merchant terms applicable to the transaction of the user. The server 120 then retrieves the URL link from the user and then accesses the URL link to locate a web page on which the first version of the online merchant terms is presented. The server 120 may then download the online merchant terms, for example, by copying the body of that web page. Alternatively, the server 120 may request the user to provide the online merchant terms applicable to the transaction of the user, when the server 120 is unable to retrieve, from the merchant device 140 and a third-party associated with the merchant, the online merchant terms applicable to the transaction of the user.

In some embodiments, the server 120 may retrieve the online merchant terms by calling an application programming interface (API) through which the first version of the online merchant terms is accessed by the server (block 330). If the merchant has an API available, the server 120 may call the API to retrieve the online merchant terms. When there is a third-party service that aggregates those APIs of merchants, the server 120 may call the third-party service and download lots of online merchant terms via those APIs.

In some embodiments, the server 120 may retrieve the online merchant terms by web-crawling the World Wide Web to locate a web page (web-hosting server 2) on which the first version of the online merchant terms is presented (block 340). The server 120 may use a web crawler starting with a list of URLs until the online merchant terms are identified. Various crawling techniques may be used, such as URL normalization, path-ascending crawling, focused crawling, academic-focused crawling, and semantic focused crawler. In web crawling, an algorithm may be created to attempt to find a merchant from a merchant domain that may be associated with their merchant identifier or merchant record in the database 130. The server 120 may also start from a type of web searching engine and search for the merchant. The server 120 may also use a script that works as a web crawler, but looks for online merchant terms. The script may be executed to follow various URLs within a merchant domain and find something that indicates that either the online merchant terms page is identified or that a link to the online merchant terms is identified. If that link is identified, the script may be executed to load it and copy the body of that page.

FIG. 4 illustrates a portion of an example transaction history of a user. Each transaction is assigned a URL link to the online merchant terms of corresponding merchant stored in the database 130. The user may click on the URL link to view the online merchant terms. In a case where the URL is a URL containing query parameters, when the user clicks on the embedded URL link to submit the URL request to the server 120, the sever 120 may search the database 130 for the online merchant terms according to the query parameters. When the server 120 gets the online merchant terms matching the query parameters, the server 120 returns the online merchant terms to the user device 110 that is configured to present the online merchant terms to the user. For example, upon receiving the online merchant terms by the user device 110, the user device 110 can present via a web browser installed on the user device 110 to user a web page containing the received online merchant terms.

In a case where the URL is a regular URL that does not contain query parameters, when the user clicks on the embedded URL link to submit the URL request to the server 120, the server 120 may locate the online merchant terms as specified in the location path of the URL. In this case, the server 120 may further determine whether the located online merchant terms are still effective on the transaction date, for example, by examining a date (e.g., an expiration date) of the located online merchant terms. When the server 120 gets the online merchant terms, the server 120 returns the online merchant terms to the user device 110 of the user that is configured to present the online merchant terms to the user. For example, upon receiving the online merchant terms by the user device 110, the user device 110 can present via a web browser installed on the user device 110 to the user a web page containing the received online merchant terms.

FIG. 5 illustrates a portion of another example transaction history of a user. In this example, instead of URL links, each transaction is associated with at least one button. The at least one button may include one button referring to the online merchant terms involved in that transaction. For example, when the user determines to view the online merchant terms of merchant-1 for the time of his transaction, the user can click on the button 510. In response to the clicking, the server 120 transmits the appropriate online merchant terms of merchant-1 for display to the user, for example, as shown in block 515. In some situations, the online merchant terms of a merchant involved in a transaction may not be available in the database 130. For example, for the transaction involved the merchant-2, a message as shown in block 535 may be displayed to the user when the user clicks on the button 530 to view the online merchant terms-2. In such scenario, the example transaction history interface may be provided with additional buttons, such as buttons 520 and 540 for the user to provide the online merchant terms. For example, when the user clicks on the button 540, a message as shown in block 540 may be displayed for the user to have the user provide, for example, a URL link to the online merchant terms-2. In response to receiving the URL link provided by the user, the server 120 may retrieve the online merchant terms-2 by following the user provided URL link as described in the step 205 of FIG. 1 . The server may then store the retrieved online merchant terms in the database 130 and associate it in the database 130 with the merchant-2 and the transaction involved the merchant-2 (e.g., through the button 530) as described in the FIG. 1 . As another example, the user may upload a document containing the terms.

The online merchant terms may be stored in the database 130 in various document formats, including but not limited to, a text file (e.g., a plain text format), a structured data format (e.g., a XML document and/or a JSON document), and so forth. In addition, the online merchant terms may also be stored as a PDF file, an image file (e.g., a scanned image file and/or a picture file), an audio file, a video file, and/or an audio-video file in a file storage location such as a cloud storage offered by a cloud computing service provider. The database 130 may store links to the files stored in the file storage location.

For example, when the online merchant terms are stored in PDF format, the online merchant terms can be displayed on the user device 110 as a PDF file for reading by the user. When the online merchant terms are stored in a video format, the online merchant terms can be played on the user device 110 for viewing by the user. When the online merchant terms are stored in a scanned image format, the online merchant terms can be displayed via an image application program on the user device 110 for viewing by the user. When the online merchant terms are stored in an audio format, the online merchant terms can be played on the user device 110 for listening by the user.

As described above, the online merchant terms of various merchants involved in user transactions can be retrieved and stored in a data store (e.g., the database 130) for the users to view when the users check their transaction histories. Each of those transactions could have an inline link (e.g., URLs and/or buttons) where the users are able to click on it and see the online merchant terms on file in the system 100 associated with their transactions. Those online merchant terms were applicable at the date of their purchases, which are binding for that specific purchase. The users can do what they desire upon viewing the online merchant terms. For example, the users can look through those online merchant terms and attempt to get a refund or ship things back. They can attempt to get the merchant to abide by or be bound by the online merchant terms of that merchant that were applicable at that time of their purchase. They can also provide an authoritative source to the merchant to warrant what the users desire, for example, by pointing the merchant to the online merchant terms stored in the database 130. As such, this disclosure may provide a layer of protection for users when they deal with the merchants involved in the transactions.

In some embodiments, the online merchant terms stored in the database 130 may be needed to keep up-to-date. For example, to keep the online merchant terms stored in the database 130 up-to-date, a new version of the online merchant terms may be retrieved by the server 120 and is analyzed against the previous version on file in the database 130 to check for differences. If there are no differences, the recently retrieved online merchant terms are discarded. If there are differences, the version of the recently retrieved online merchant terms becomes the latest version of the online merchant terms and is stored in the database 130. The listed date range for the previous version may be adjusted accordingly. A new date range may be assigned to the latest version of the online merchant terms. This new date range has a start date on which the recently retrieved version is retrieved. The previous version may be discarded if there have no any transactions associated with it, which may reduce the need for storage space. However, the previous version may be retained if there have at least one transaction associated with it. If the previous version is retained, a new end date may be assigned to the date range previously listed for the previous version. This new end date of the previous version may be the date on which the recently retrieved version is retrieved. That is, this new end date of the previous version is the start date of the latest version, such that a new version of the online merchant terms (i.e., the latest version different than the previous version) is assigned a start date of the date on which the recently retrieved version is retrieved, and the previous version is assigned an end date of the date on which the recently retrieved version is retrieved.

FIG. 6 illustrates a method 600 of retrieving online merchant terms of a merchant and associating the online merchant terms with the merchant in a data store according to an example embodiment. The method 600 may be used to keep the online merchant term stored in the database 130 up-to-date. FIG. 6 may reference the same or similar components as those illustrated in FIGS. 1-5 , including a user device, a server, a database, and a merchant device.

In step 605, the server 120 may retrieve a second version of the online merchant terms. As described in FIG. 2 , the first version of the online merchant terms has been retrieved and stored in the database 130. To keep the online merchant terms up-to-date in the database 130, the server 120 may retrieve the second version of the online merchant terms. The retrieving techniques used for retrieving the second version can be the same as or similar to the retrieving techniques described for the first version in FIG. 2 . For example, the retrieving of the second version can be based on a cached URL link that is used to retrieve the first version. If the cached URL link is broken, then web crawling for the second version may be needed. Retrieving of the second version of the online merchant terms may occur based on a pre-configured triggering condition (e.g., at a pre-specified time interval, or when an event occurs to the merchant).

For example, the server 120 may retrieve a second version of the online merchant terms every day, every hour if more frequently is desired, every week or every month if less frequently is desired, even every year, or the like. The server 120 may also retrieve the second version of the online merchant terms based on merchant importance and/or transaction volume. For example, the server 120 may web crawl more frequently a popular merchant or a merchant involved in more transaction volume to see when their online merchant terms change, whereas the server 120 may web crawl less frequently a merchant involved in a small transaction volume to see if its online merchant terms change (e.g., every three years for a merchant having only two transactions in the past one year).

In some embodiments, retrieving of the second version of the online merchant terms may be triggered at a time when an event occurs, for example, changes in regulation/law relevant to the merchant, company acquisitions/merge/sale involving the merchant, email triggers, etc.

In some embodiments, retrieving of the second version of the online merchant terms may be triggered based on whether the first version of the online merchant terms has been verified during a pre-configured past time period, for example, the past 3 months. For example, in addition to the time stamp assigned to the first version in the database 130 where the time stamp indicates a retrieving date of the first version, the first version of the online merchant terms may also be assigned a latest verification date or the like. The latest verification date is a date during the pre-configured past time period when the first version is last checked whether the first version was still effective.

In step 610, the server 120 may compare the second version of the online merchant terms with the first version of the online merchant terms to determine a latest version of the online merchant terms. The comparison may be a textual comparison. In some examples, whitespace and the additional of new lines, punctuation, or other special characters can be ignored. The determined latest version may be the first version if no difference is identified between the first version and the second version, or may be the second version if at least a difference is identified. In some embodiments, checksums or hashes may be validated to determine if the first version and the second version are the same, which may be particularly applicable if the online merchant terms are shown in a file, instead of being on a webpage. Additional detail about determination of the latest version will be described with reference to FIG. 7 .

In step 615, the server 120 may store in the database 130 the latest version of the online merchant terms. The latest version of online merchant terms may be further formatted and indexed in the database 130. The latest version of online merchant terms may be stored in the database 130 as various forms, which may include but not limited to, a text file (e.g., a plain text format), a structured data format (e.g., a XML document and/or a JSON document), and so forth. In addition, the latest version of online merchant terms may also be stored as a PDF file, an image file (e.g., a scanned image file and/or a picture file), an audio file, a video file, and/or an audio-video file in a file storage location such as a cloud storage offered by a cloud computing service provider. The database 130 may store links to the files stored in the file storage location.

In step 620, the server 130 may apply a latest version time stamp to the latest version of the online merchant terms, wherein the latest version time stamp is indicative of a retrieval time and a retrieval date at which the latest version of the online merchant terms is retrieved. In step 625, the server 120 may associate the latest version of the online merchant terms with the merchant in the database 130. In step 630, the server 120 may assign the latest version of the online merchant terms a second date range in the database, wherein the second date range is indicative of a date range when the latest version of the online merchant terms is effective in the database 130. Details of the above steps can be referred to the similar steps in FIG. 2 described for the first version of the online merchant terms.

The step 610 in which the server 120 compares the second version of the online merchant terms with the first version of the online merchant terms to determine a latest version of the online merchant terms may be explained in detail in FIG. 7 . FIG. 7 describes a method 700 of comparing the first version and the second version of the online merchant terms according to an example embodiment. FIG. 7 may reference the same or similar components as those illustrated in FIGS. 1-6 , including a user device, a server, a database, and a merchant device.

In step 710, the server 120 may analyze the second version of the online merchant terms against the first version of the online merchant terms in the database to identify a difference between the first and second versions of the online merchant terms. For example, a textual comparison may be performed between the first version and the second version for the body text of the online merchant terms. The comparison analysis can include what is added to the second version, what is changed to the first version, and the like. There may be certain things that may not considered as a difference, for instance, space changes, additional new lines, added space and tab, punctuation, or other special characters, and the like.

In step 720, it is determined whether there have differences between the first version and the second version. If there have at least one difference (i.e., “YES” branch is selected), the method 700 proceeds to the step 730. If there have no differences (i.e., “NO” branch is selected), the method proceeds to the step 740.

In step 730, the server 120 determines the second version of the online merchant terms as the latest version of the online merchant terms. The first version may be discarded if there have not been any transactions associated with it, which may reduce the need for storage space. However, if there have transactions that are still associated with the first version, the first version of the online merchant terms may be retained in the database 130 and remains associated with the applicable transactions. Then the server 120 may assign a new date range as the second date range for the latest version. This new date range may be assigned a start date on which the second version is retrieved. The first version may be further assigned a cut-off date (i.e., a new end date of the first version) indicating that the first version is no longer valid because changes have been made to the first version. The cut-off date of the first version may be the retrieval date and time of the second version, or may be a date earlier than the retrieval date and time of the second version. In such scenario, there may have multiple versions of the online merchant terms of that merchant in the database 130.

If no applicable transactions are associated with the first version any more in the database 130, the first version of the online merchant terms may be removed from the database 130 and discarded. Then the server 120 may simply update the first date range of the first version to the second date range that is to be associated with the latest version of the online merchant terms. The first version of the online merchant terms may also be archived for reference in the future.

In some embodiments, the server 120 may notify the user of the differences or changes made to the online merchant terms based on a pre-configured condition of the user, wherein the pre-configured condition of the user may comprise an identification of a difference between the second version of the online merchant terms and the first version of the online merchant terms. The server 120 may also simply notify, for example, using text message, the user of a change having been made to the online merchant terms without further details on what the change is. The pre-configured condition of the user may also comprise a time period specified by the user. For example, the user may indicate that for any merchant that he or she has purchased things from in the last six months, he or she desires to be notified when the online merchant terms of that merchant change.

In step 740, the server 120 may discard the second version of the online merchant terms and determine the first version of the online merchant terms as the latest version of the online merchant terms because no difference is identified and the second version is just a repeat of the first version. However, the server 120 may assign a verification date to the first version. The verification date can indicate that the online merchant terms have been retrieved again and are still in effect without changes on the verification date.

In some embodiments, when the second version of the online merchant terms is determined as the latest version of the online merchant terms in step 730, the first version of the online merchant terms may be replaced with the second version of the merchant terms in step 750.

In some embodiments, when the second version of the online merchant terms is discarded and the first version of the online merchant terms is determined as the latest version of the online merchant terms in step 740, the first version of the online merchant terms is retained in step 760.

In step 770, the database 130 is updated accordingly. For example, the database 130 removes the first version of the online merchant terms when the second version of the online merchant terms is determined as the latest version of the online merchant terms, and no transactions were associated with the first version. For another example, when the second version of the online merchant terms is discarded and the first version of the online merchant terms is determined as the latest version of the online merchant terms, the database 130 may assign a new date range to the first version of the online merchant terms.

After the latest version of the online merchant terms is stored in the database 130, new transactions may be associated with the latest version of the online merchant terms. FIG. 8 describes a method 800 of associating the latest version of the online merchant terms with a new transaction (referred to as a second transaction) according to an example embodiment. FIG. 8 may reference the same or similar components as those illustrated in FIGS. 1-7 , including a user device, a server, a database, and a merchant device.

In step 805, the server 120 may receive information of a second transaction of the user to identify a transaction time and a transaction date of the second transaction. The information of the second transaction may comprise the transaction time and the transaction date of the second transaction and a merchant identifier indicating the second transaction as be a transaction from the merchant. The transaction time and the transaction date of the second transaction are identified by extracting the transaction time and the transaction date of the second transaction from the information of the second transaction.

In step 810, the server 120 may determine whether the latest version of the online merchant terms is applicable to the second transaction of the user, based on the time stamp of the latest version of the online merchant terms, the second date range, and the transaction time and the transaction date of the second transaction. Details of this step may refer to the similar description of step 240 in FIG. 2 .

If the “YES” branch is selected in step 810, the method 800 proceeds to step 815. In step 815, the server 120 may associate in the database 130 the latest version of the online merchant terms with the second transaction upon determining that the latest version of the online merchant terms is applicable to the second transaction. In step 820, responsive to receipt of a selection of viewing online merchant terms associated with the second transaction, the server 120 may transmit the latest version of the online merchant terms for display to the user. Details of the above steps may refer to the similar description of steps 245 and 250 in FIG. 2 .

If the “NO” branch is selected in step 810, the method may proceed to step 825. In some embodiments, some prior transactions may be flagged as not having been associated with any online merchant terms, or may be associated with incorrect online merchant terms (e.g., the association could be due to the wrong effective dates of online merchant terms, online merchant terms from the wrong merchant, etc.). In such scenario, in step 825, the server 120 may determine whether a prior version of the online merchant terms exists and whether the prior version of the online merchant terms is applicable to a prior transaction or a different transaction (e.g., the first transaction of the user), based on the time stamp of the latest version of the online merchant terms, the second date range, and the transaction time and the transaction date of the first transaction. Details of this step may refer to the similar description of step 240 in FIG. 2 .

In step 830, the prior version of the online merchant terms may be associated in the database 130 with the first transaction upon determining that the latest version of the online merchant terms is not applicable to the first transaction. In step 835, responsive to receipt of a selection of viewing online merchant terms associated with the first transaction, the server 120 may transmit the first version of the online merchant terms for display to the user. Details of the above steps may refer to the similar description of steps 245 and 250 in FIG. 2 .

As described above, a user may use the user device 110 to check their transaction history and to view the online merchant terms associated with the transaction. FIG. 9 describes a method 900 of viewing online merchant terms on the user device 110 according to an example embodiment. FIG. 9 may reference the same or similar components as those illustrated in FIGS. 1-8 , including a user device, a server, a database, and a merchant device.

In step 905, the user device 110 may display a user login interface on the display 114 of the user device 110. The login interface may be presented in a web browser of the application 113. The login interface may comprise an interface for logging into the server 120.

In step 910, the user device 110 receives user credential entered by the user into the user login interface. When the user determines to check their transaction history and to view the online merchant terms associated with the transactions, the user can enter his login credential, such as user name and password, on the login interface. For example, the user may want to find out whether he or she can return his purchase and get a refund according to the online merchant terms stored in the database 130.

In step 915, the user device 110 may transmit the user credential to the server 120 for being authenticated by the server 120. After receiving the user login credential, the device 110 transmit the user login credential to the server 120 for authentication. Such communications between the device 110 and the server 120 may be performed through the secure back channel of the network 150 as described in FIG. 1 above. Such communications may also be encrypted for further security.

In step 920, the user device 110 may display a user transaction interface on the display 114. The user interface may comprise at least one transaction associated with the user and a merchant, and one or more options regarding accessing online merchant terms. Exemplary user transaction interfaces may include the diagram shown in FIG. 4 and the diagram shown in FIG. 5 .

In step 925, the user device 110 may receive, from the server, the online merchant terms in response to a selection by the user of an option from the one or more options. The selected option can be an option of reviewing the online merchant terms. For example, the user may click on a URL link in FIG. 4 or a “view terms” button in FIG. 5 . Upon such selection, the server 120 may transmit the online merchant terms associated with the transaction to the device 110, as described in step 250 in FIG. 2 .

In step 930, the user device 110 presents the online merchant terms on the display 114 to the user. Upon receiving the online merchant terms from the server 120, the user device 110 display the online merchant terms to the user, such as in block 515 in FIG. 5 .

In some embodiments, a user transaction may be declined to further protect the user if online merchant terms are not applicable or unavailable in the database 130 to that transaction. For example, the user may attempt to buy something expensive (e.g., over a certain price threshold) or of a certain type or category of product or service (e.g., a smartphone or another electronic device), and no online merchant terms are applicable or available in the database 130 to that transaction, that transaction may be declined. The server 120 may further send the user a message indicating that no online merchant terms are applicable or available on file at this moment and the server 120 is proactively looking them up. The sever 120 may then send the user another message once the online merchant terms are retrieved and stored in the database 130, such that the user can try the declined transaction again.

The certain type or category of product or service may be a type or category of product or service that presents a high risk to the user's life or health. An exemplary service of such category may be aerial sports such as parasailing. The certain type or category of product or service may be a type or category of product or service that exhibits a high value. An exemplary product of such category may be high end jewelries such as diamond or gold. The certain type or category of product or service may be a type or category of product or service that bears a potential high risk to the user's financial condition. An exemplary service of such category may be an advertised low fee and high return investment service or product.

Alternatively, the user may be provided an option of whether he or she wants to proceed with the transaction and/or whether he or she can provide the online merchant terms that are applicable to that transaction (e.g., the user may provide a URL link to the online merchant terms or a copy of the online merchant terms). Alternatively, if the merchant involved in the transaction has never been recognized by the server 120, the transaction may be initially declined while the server 120 attempts to go collect the online merchant terms and/or send the user a message of what is happening.

Alternatively, when online merchant terms are not applicable or unavailable in the database 130 to a transaction, the server 120 may determine whether to approve the transaction or decline it based on a transaction price threshold. For example, if the transaction was over $50, it may be declined. Whereas if the transaction was less than $50, the transaction may be approved.

In some embodiments, a transaction may be a recurring transaction, for example, rental fees for apartment rental, subscription to software service, and the like. The server 120 may monitor the online merchant terms to see whether or not they have been changed. In this respect, the server 120 may cross-reference the terms with the merchant of the recurring transaction with the merchant's terms at the last time that the recurring charge was incurred, and if the server 120 registers that the merchant has changed their terms, the server 120 can proactively alert the user of the change of the terms. The alert can be sent to the user either at the time that a change of the terms is identified or at the time proximate to expect the user to be charged again. For example, if the user gets charged the 8^(th) of every month, then the alert can be sent to the user on the 6^(th) of every month, notifying the user that this merchant has changed their online merchant terms. Therefore, the user can be provided with an opportunity for making a change to the recurring transaction, such as cancelling the service, changing to another type of service, and the like, prior to incurring an additional charge.

In some embodiments, a natural language processing (NLP) model may be used to process online merchant terms, for example, to identify an effective date of the online merchant terms. For example, a transaction may have occurred before the first version of the online merchant term of that merchant was retrieved and stored in the database 130. In such scenario, the server 120 may use the NLP model to identify when the online merchant terms went into place. For example, the NLP may be used to search for things like “Effective Date Jan. 1, 1999” or “Document Last Updated Feb. 1, 2010” in the online merchant terms. If the online merchant terms are identified to be in effect earlier than the transaction date and the transaction time of the transaction, the online merchant terms can be retroactively applicable to the transaction and can be associated with the transaction in the database 130, even though the online merchant terms are retrieved and stored in the database 130 later than the transaction. Therefore, there may be in the database 130 multiple versions of the online merchant terms of a merchant, which may be chronologically organized and put in place for retroactive transactions.
